Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden to disclose behavioral traits. It says nothing about side effects, required authentication, rate limits, or whether the post creation is immediate. The mere statement 'Create a Reddit post' is insufficient.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence, which is concise but severely underspecified. While it earns its place by stating the core purpose, it lacks necessary details to be considered appropriately sized for a tool with 8 parameters.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity (8 parameters, 4 required) and no output schema, the description is incomplete. It fails to explain return values, authentication requirements (access_token), or how choose post type (kind), leaving significant gaps for the agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has 8 parameters with only 13% description coverage (only the 'kind' parameter has a description). The tool's description adds no information about parameters such as access_token, subreddit, title, text, url, nsfw, or spoiler, leaving the agent to rely on parameter names alone.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Create a Reddit post.' clearly states the verb (create) and the resource (Reddit post), and it naturally distinguishes from sibling tools like reddit_comment, reddit_read, etc., which perform different actions.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives such as reddit_comment or reddit_search. The description does not mention when not to use it or any prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
